gene APX1, overexpression CsAPX1 in Arabidopsis thaliana | Camellia sinensis |
Protein Variants | Comment | Organism |
---|---|---|
additional information | overexpression CsAPX1 in Arabidopsis thaliana indicates that the decrease of AsA content and APX activity in transgenic lines is less significant than that of the wild-type during postharvest storage under light/dark conditions | Camellia sinensis |

General Information | Comment | Organism |
---|---|---|
metabolism | enzyme ascorbate peroxidase 1 (CsAPX1) is involved in ascorbic acid (AsA) metabolism | Camellia sinensis |
physiological function | ascorbate peroxidase 1 regulates ascorbic acid metabolism in fresh-cut leaves of tea plant during postharvest storage under light/dark conditions. CsAPX1 is involved in regulating AsA metabolism through effecting on the changes of AsA accumulation and APX activity in the leaves | Camellia sinensis |
